Markets like certainty, and the 2016 election results are anything but certain. Global markets were caught off-guard and are now in disarray.

Dow futures are down more than 780 points around midnight Eastern Time. If that sticks into trading on Wednesday, it will be comparable to the darkest days of 2008 — in the midst of the financial crisis. For comparison, the Dow lost 778 points (about 7 percent) on Sept. 29, 2008, its worst day in history.

S&P 500 futures (another U.S. stock index) were down about 5 percent at midnight Eastern Time.

The exchange rate between the U.S. dollar and the Mexican peso — a bellwether for this election cycle — has plunged more than 11.5 percent as of midnight Eastern Time. It’s the biggest intra-day drop since 2008, according to Bloomberg Markets.
